This architecture uses FEC coding and ARQ [1] protocol to provide efficient bandwidth access from wireless link. In order to reduce ARQ delay, a video proxy server is implemented at the base station. This video proxy not only reduces the ARQ response time but also provides error tracking functionality. We use H.263[2] as the experimental platform for our architecture. Experiments show that average luminance PSNR decreases only 0.35db for the "Foreman" sequence under a random error condition of 10-3error probability. © 2002 IEEE. |
